(Cl. 7210l) 6 Claims.

This invention relates to building construction and more particularly to the permanent aflixa- .tion of preformed insulating material to the walls and ceilings thereof.

In the construction of buildings or rooms in which a constant temperature is desired, such as cold storage rooms, it is common to sheathe or cover the walls with slabs of suitable granulated or cork insulating material, such as crushed or shredded cork, or rock, or mineral wool, the particles of which are held together by suitable binding material. The most common method of aflixing insulating slabs to all surfaces is to affiX them with hot asphalt or other cement which, in the course of time, deteriorates permitting the slabs to fall away from the wall. An improved method is by positive aflixation to concrete as disclosed in the patent to Wilson No. 1,967,071.

One of the objects of this invention is to provide an improved method of afiixing insulating slabs to concrete walls by ties which are integral with the wall.

Another object of this invention is to provide an improved tying member for affixing insulating material to building or chamber walls.

Another object of the invention is to provide an improved means for removably aflixing and replacing insulating slabs to concrete walls by ties which are integral with the wall.

Another object of the invention is to provide an improved tie for affixing insulating slabs to concrete walls, which tie may be constructed in the wall prior to the aflixation of the insulating material.

Other objects of the invention will be apparent fro mthe description and claims which follow.

The word wall as employed in this specification and in the claims which follow is used in the broad sense and includes exterior walls, chamber partitions, floors, ceilings, barriers, and the like.

In the accompanying drawing similar refer ence characters in the several figures indicate similar parts throughout the entire specification.

Figure 1 is a. front view of the improved tie of the present invention.

Figure 2 is a perspective view partly in section of a concrete floor provided with a layer of in-- sulating material applied in accordance with the present invention.

Figure 3 is a sectional view of a concrete wall insulated in accordance with the present invention.

Broadly, the invention comprises substantially U-shaped wall tie I provided with outwardly flared, tensionable stem portions 5 and 6. In the specific embodiment shown in Figure 1, wall tie l consists of substantially semicircular loop or curved portion 4 joining substantially parallel, longitudinally opposed stem portions 2 and 3, each of the stem portions 2 and 3 at a point remote from its free end being bent to form outwardly flared stem portions 5 and 6, respectively. Stem portions 5 and 6 at their free ends preferably are pointed or flattened to a penetrating edge to facilitate their insertion into the insulation slab. It is important that the wall tie be made of spring-steel wire or other similar material in order that stem portions 5 and 6 may be laterally pressed in substantially parallel alignment preparatory to initial penetration of stem portions 5 and 6 into the insulation material and further in order that following initial penetration of stem portions 5 and 6 into the insulation material and the release of pressure thereon, stem portions 5 and 6 will forcibly spread outwardly coincidentally with further passage into the insulation material.

A portion of a concrete floor is shown in Figure 2. It will be observed that the floor comprises the ordinary concrete floor 9. To this floor is afiixed a layer of insulating material consisting of preformed slabs Ill. The curved portion ll of the tie I is placed over the metal red I l, which rod, together with the curved portion of the tie 4 and the parallel stems 2 and 3 of tie I, become embedded in the concrete slab when completed. The diverging or outwardly flaring ends 5 and 6 are pushed into the insulating slab H3.

A section of a concrete vertical wall or partition is shown in Figure 3 in which it will be seen that no reinforcing rods are employed.

Many methods of construction will be readily apparent to those familiar with the art but in the preferred embodiment of this invention, I use preformed insulating slabs, which are assembled in place in any suitable manner; and in the case of floor construction after reinforcing rods are laid, the tying devices are applied in the manner shown in Figure 2 whereby the loops remain outside of the insulating material, upon which the concrete or like material is poured.

Another method of construction would be to place the curved portion of the tie around the reinforcing bars for the concrete wall, permitting the outwardly flaring ends to extend through the form material; pouring the concrete or like material in the necessary forms; and after such concrete has set and the forms have been removed, the curved and parallel stem portions will be firmly aflixed in the wall and the diverging ends will be outside of the wall; thereafter the insulating slabs, preferably with backs and edges covered with asphalt, are then pushed against the points of the ties until the slabs are tight against the wall.

Still another method would be to affix the slabs of insulating material to a wall construction of brick, hollow tile or other similar material, either by building such wall against the previously assembled slabs of insulating material to which the ties have been aflixed as above described, or by placing the semi-circular loop and the parallel stem of the tie in the wall as construction progresses, leaving the diverging outer ends extending outside the Wall, and thereafter affixing the insulated material to the wall by means of pressure which pushes the tie into the'insulating material.

Any of the above types of construction result in a relatively continuous layer of heat insulating material which is held in place on the wall by the functioning of the tying member herein described.

One type of insulating material suitable for use in connection with this invention is a com- 5:

mon type of granulated cork or shredded, ground or otherwise disintegrated rock or mineral wool,

particles of which are held together with a suitable binder and which are formed into slabs of various sizes.

It is desirable to have the ties herein described made of metal, as the construction for which they are used is usually permanent, and it is desired that the ties shall not deteriorate in the course of time. It is preferable that the tying members be made of a material which will be relatively strong and will not be easily broken during the construction of the wall.

What is claimed is:

1. A wall tie curved in U-shape with parallel wire stems adjacent to the curved portion, said stems being provided with outwardly flared ends, the curved portion of said tie being adapted to be embedded in a wall, and the end portions being adapted to be moved by pressure into substantially parallel relationship for insertion into an insulating slab and to spread outwardly in the insulating slab upon release of the pressure.

2. A wall tying device comprising a semi-circular wire loop, and integral wire stems parallel for a portion of their length adjacent to the loop and terminating in outwardly flared ends, the loop and parallel stem portions being adapted to be embedded in a wall, and the end portions being adapted to be moved by pressure into substantially parallel relationship for insertion into an insulating slab and to spread outwardly in the insulating slab upon release of the pressure.

3. An integral spring tensionable wall tie comprising a curved portion joining a pair of parallel, longitudinally opposed wire stem portions, each of the stem portions remote fromits free end being angularly outwardly flared, the curved portion and parallel stem portions being adapted to be embedded in a wall and the outwardly flared end portions being adapted to be moved by pressure into substantially parallel relationship for insertion into an insulating slab and to spread outwardly into an insulating slab upon release of the pressure.

4. An integral spring tensionable wall tie comprising a curved portion joining a pair of parallel, longitudinally opposed wire stem portions, each of the stem portions remote from its free end being angularly outwardly flared, and each of the stem portions at its free end being provided. with a penetrating edge, the curved portion and parallel stem portions being adapted to be embedded in a wall and the outwardly flared end portions being adapted to be moved by pressure into substantially parallel relationship for insertion into an insulating slab and to spread outwardly into an insulating slab upon release of the pressure.

5. An integral wall tie comprising a springsteel wire member having a portion curved in U- shape and having parallel stems adjacent to the curved portion, each of the stems being provided with relatively long, outwardly flared ends, the curved portion of said tie being adapted to be embedded in a wall, and the end portions being adapted to be moved by pressure into substantially parallel relationship for insertion into an insulating slab and to spread outwardly in the insulating slab upon release of the pressure.

6. A wall tie comprising a semi-circular springsteel wire portion joining a pair of parallel longitudinally opposed stem portions, each of the stem portions remote from its free end being angularly outwardly flared, and each of the stem portions at its free end being provided with a penetrating edge, the curved portion and parallel stem portions being adapted to be embedded in a wall and the outwardly flared end portions being adapt-ed to be 'moved by pressure into substantially parallel relationship for insertion into an insulating slab and to spread outwardly in the insulating slab upon release of the pressure.
